But he is right, we have some interesting laws. For example, if you have an actor that is over 18 but looks to young or is depicted as a child in porn then that is illegal. All that weird japanese hentai crap with octopus's and aliens banging women is illegal. It's also to depict something that is illegal, so if you draw a picture of a cantabrian shagging a sheep - that is potentially objectionable material.
Also nobody nowhere has indicated it is CSAM.
